Edit together in PowerPoint Online

In OneDrive, click to open the file that you want to work on with others.

Under Edit Presentation, click Edit in PowerPoint Online.

Begin working on your presentation.

If others are working on the presentation at the same time, you’ll see a co-authoring icon
and a number in the status bar that tell you how many people are working on the presentation. Click the down arrow next to the co-authoring icon to see who is working on the presentation.

When people are editing the presentation without signing in to OneDrive or SharePoint, they show up in the list as "Guest".

If they're also using PowerPoint Online, you can even see what they're typing in real-time, and an indicator that shows you what slides they're working on.

You can co-author with people who use the PowerPoint desktop application. However, for best results, people using PowerPoint Online should take turns making changes with those using the PowerPoint desktop application (PowerPoint 2010 or later, or PowerPoint for Mac 2011 or later).

Kinds of co-authoring

Real-time co-authoring is when two or more people type and the text changes for everyone at the same time. With real-time co-authoring, you can see the cursor location of the other editors on your screen. Formatting changes show as well. If you co-author with someone who's using a version that supports only regular co-authoring, you won't see edits from them in real time.

Regular co-authoring is when you and others can simultaneously work on a document, and not block each other. You can see who else is working on the document. While a co-author is editing a paragraph, that paragraph is locked from editing by others. When new changes are made by others, you see an Updates Available status in your document or presentation. When you save, you see changes that others have made. Your document is refreshed, on save, with changes that everyone else has saved since the last time you saved. If you're using an application supporting regular co-authoring, you can co-author with someone who's using a version that supports real-time co-authoring.
